PUMP ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 232,143, datedSeptember 14, 1880.

Application filed June 12, 1880.

To all whom. it may concern:

Be it known that I, IsAAo H. PALMER, of Lodi, in the county of Columbiaand State of Wisconsin, have invented a new and valuable Improvement inWVindmill Pump Attachments; and I do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawing,making a part of this specification, and to the letters and figures ofreference marked thereon.

The drawing is a representation of an elevation of my improved pump,partly in section.

Thisinvention has relation to improvements in windmillpump attachments.

The object of the invention is, in pumps operated by wind-en glues, todevise means whereby they may be worked by hand without, in the upstrokeof the piston-rod of the pumps, having to raise the superineumbentweight of the mill-plunger and its connections when the wind fails.

The nature of the invention will be hereinafter more fully set forth.

In the annexed drawing, the letter A desig nates the pump-cover, B thepump, and C the frame, through which reciprocates the plunger I) insuitable guides on b.

D indicates the piston-rod of the pump, connected to the lower end ofthe plunger, reciprocated bythe wind-engine through the medium of theknee-jointed connecting-rods Gr G, pivoted to vibrate in the same planerespectively to the said piston-rod and to the plunger, and connected toeach other by a rule' or other joint in such manner that while they willfreely flex in one direction they are practically rigid as regardsbending in theother.

It is evident that the reciprocation of the plunger will work the pump.

H indicates a rocking standard pivoted to an offset, 0, of the top ofthe pump, and afford ing a fulcrum to the handle-lever I in its upperend. This lever is of equal weight at each side of its fulcrum, and itsweight end is pivoted to a projecting lug or arm, 11, extending outwardfrom the rod Gr slightly above its connection to the piston-rod of thepump.

(No model.)

The lever I being evenly balanced on the standard H, no appreciableadditional power is required to carry it when the wind-engine is atwork.

Instead of the oscillating standard I may use a fixed one by connectingthe weight end of the lever I to the lug (l on rod Gr.

Should the wind fail the pump may be worked by operating the lever I,when its weight end purchases upon the lug d and flexes and straightensthe rods G G, thus actuating the pump-piston without raising theplunger.

I am aware that oscillating standards for the levers of hand-pumps havebeen used before; hence I do not claim this feature broadly.

As the pump-piston in this description of pumps must have some play, thediameter of the hole in the cap must be made considerably greater thanthat of the said rod, and I prevent bugs and insects from getting intothe pump by means of a washer, a, resting loosely on the pump-cap andencircling the piston-rod. This washer is of greater diameter than thehole in the cap, and follows the piston during its play, at all timescovering the said hole.

WVhat I claim as new, and desire to secure by Letters Patent, is-

1. In a pump operated by a wind-engine, the combination, with the pistonD and the reciprocating mill plunger D, of the knee.- jointedconnecting-rods G G and a pump-handle fulcrumed on the pump andconnected to the rod Gr, substantially as specified.

2. The combination, with a pump-piston rod and a reciprocating plunger,D, of the kneejointed rods G G, connecting said rod and plunger, theoscillating standard H upon the pump, and the lever I, fulcrumed on saidstandard and pivoted to an oflset, d, of the pump, substantially asspecified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

ISAAC H. PALMER.
